Product usage:
BD726 high temperature wear & corrosion resistant coatings is the high performance high-temperature & wear & corrosion resistant polymeric ceramic material compounded by high performance wear resistant,corrosion resistant material (like ceramic,silicon carbide,carborundum,titanium alloy etc.) and modified toughening heat resistant resin.Widely used in the preparation of wear & corrosion resistant coating on the surface of various machine part which has high temperature,wear resistant,corrosion resistant requirements.The highest temperature resistant is 250℃.

How to use:
1.Surface treatment:Do coarsening treatment on the pending-repair part,grinding with angle grinder or sand blasting etc,the surface after coarsening treatment should be cleaned,the surface after this treatment should be the one coarsening,dry and fresh substrates,should be no greasy dirt and dust.

2.Preparation:According to weight ratio 4:1,make A and B two components mix uniformly,and use it up within 40 min.Generally it’s while construction and configuration.Every time the most configuration quantity is not more than 2Kg,too much adhesive is solidified too fast,hasn’t been used up until the adhesive has partial solidified and can’t be used.According to the actual temperature,configuration can be properly a little more in winter and proper less in summer.If the temperature is too low,can properly heat up the A component to reduce viscosity for easy to configure.

3.Coating:The suitable coating thickness of  BD726 high temperature wear & corrosion resistant coatings  is 4-8mm.Make the mixed-up material be coating on the pending-repair part layer by layer,the first layer should be compacted,make it infiltrate fully with the substrates.Repair the surface to be smooth after the coating is coated in the suitable size,or make low viscosity wear resistant adhesive be coating on the coating surface.This material can’t do machining,should pay attention to controlling the coating thickness to avoid appearing interference phenomenon in the assembly.

4.Curing: Cure for 24 hours at the temperature of 25℃ before using,if the temperature is low,should heat it up or prolong curing time to promote the curing.General construction in winter,can use iodine tungsten lamp do irradiation heating with 40cm distance from the coating.

Special version:
1.  This parameter is for laboratory conditions,due to the actual working condition is more complex,suggest users do pretest according to actual working condition
2.  When the environment temperature is below  15℃,the curing time will prolong,should take proper heating measure
3.  When the environment temperature is more than 25℃ or the mixing quantity is too large,the curing speed will expedite,should properly shorten the application time of coating after mixing.
4. Should pay attention to reinforcing ventilation during using.


Transportation storage:
Sealed storage in the cool and dry place.The warranty period is 12 months.Avoid placing it upside down,knocking against and transporting it as a non-dangerous product during transportation.
